Abstract Scope |
TriBeam experiments have proven to be a path forward for cubic-mm scaled, micron resolution, 3D microanalytical data acquisition. In this talk we review new hardware developments that have enabled low damage laser ablation over larger (>1.5mm) fields of view, with high current (μA) Xenon plasma FIB for surface cleanup if necessary, and EBSD detectors than can capture 3000-5000 fps with greater electron sensitivity than existing systems. Sub-micron layers of material are laser ablated using the standard microscope stages and pre-tilt specimen holders. Data acquisition times have decreased with this new hardware, and the balance between reasonable acquisition times, imaging modalities, and data volumes are presented. Raw EBSD patterns are processed systematically, in parallel, using the spherical indexing method (EMSphInx) running on a co-located high performance computing center. Discussion of the advancements in the 3D data acquisition workflow, reconstruction and analysis software, and the collaborative data infrastructure BisQue will be made. |
